No dark side to using LED
lights to supplement Wi-Fi
A 12-month project
funded by the
Engineering and
Physical Sciences
Research Council
(EPSRC) has
found that LEDs
could help meet
demands for wireless
communications
Leader of research study,

quality of light or the
existing environmental benefits they deliver.
A University of Edinburgh team, lead by Dr
Wasiu Popoola, has found that transmitting
digital data via LEDs at the same time as using
them to generate light does not make the
light dimmer or even change its colour. These
popular misconceptions, explained Dr Wasiu
Popoola, have held back the more widespread
adoption of Light Fidelity, or Li-Fi, which uses
household LEDs to enable data transfer.
The research findings should help to
eliminate key hurdles to using LEDs to help
satisfy the increasing global thirst for wireless
communications. Preserving the quality of
lighting is, in particular, a vital consideration as
it has the potential to have a major effect on
the physical and mental wellbe ing of people in
both their homes and workplaces. LEDs have
secured a huge increase in their share of the
worldwide lighting market, as well as being
used extensively in TV and other displays.
Research explored two different data
transmission techniques, the first ‘on-
of keying’, whereby the LED works like
Morse code, switching on and off rapidly
and imperceptibly to human eyes; and
‘continuous signalling’, where imperceptible
changes in light intensity are used to achieve
the same goals.
With an increasing number of personal
and household gadgets connecting to
IoT, adding to the torrent of data needing
transmission and the demand for wireless
communications, Dr Popoola detailed, “Our
ever more connected world will need more
bandwidth than the overcrowded Radio
Frequency part of the spectrum can provide.
Plugging a key knowledge gap, our results are
very encouraging for the future of light-based
communications that could help realise the
full economic and social potential of a wireless
future. It’s vital that LED manufacturers
know what impact the incorporation of data
transmission capabilities would have on their
products. Our research shows that there’s no
dark side to using LED lights to supplement
Wi-Fi.”

Savvius sets out tempting
introductory incentives
Savvius says its doubling down on adoption of new high-performance
network monitoring appliances with introductory incentives. The deals
concern the company’s Omnipliance Ultra and Spotlight Appliance solutions.
Specialist in actionable network visibility, the company has announced
a limited-time promotion giving customers trade-in credits and discounts
of up to 30% off MSRP on the new Savvius Omnipliance Ultra and Savvius
Spotlight appliances. Valid through to December 15, 2017, this offer applies
to existing Savvius customers as well as enterprises using select, outdated
network monitoring or packet capture appliances from competing vendors.
“Savvius PartnerONE channel partners can now provide customers with
solutions that offer exceptional network visibility using the new Savvius
Omnipliance Ultra and Savvius Spotlight appliances,” says Patrick Johnston,
vice president of worldwide sales at Savvius.
“With this introductory incentive program, our Savvius PartnerONE
solution providers are able to deliver unprecedented value to customers
who have been looking to upgrade a legacy Savvius solution, or have
been overburdened with the support and maintenance fees of competitive
solutions offering less functionality.”
Savvius Omnipliance Ultra is designed to allow IT professionals to
quickly anticipate, identify, locate and resolve network per formance
problems. Every Omnipliance Ultra appliance includes Savvius Spotlight
technology, which goes beyond traditional dashboards by analysing every
network transaction or conversation in real time to provide instant visibility
into network trouble spots.
Using the platform, it’s easy to identify the four golden networking
signals of latency, traffic utilisation, errors and saturation, allowing IT
professionals to focus on proactively resolving the most pressing issues
before their customers complain or better still even notice there is an issue.
The Savvius Spotlight appliance brings the advantages of Spotlight
technology to a standalone appliance that supports 20Gbps of network
traffic. The Spotlight appliance can operate as a standalone device or tightly
integrate with previous- and latest-generation Savvius Omnipliances.
